1320 sq.cm
Explanation:
Diameter of the cylinder and hemisphere = 42cm => radius = 21cm
Total height of the vessel = Height of hemisphere + height of cylinder = 30cm
Height of the cylinder = Total Height - Height of hemisphere = 30 - 21 = 9cm
Inner surface area of the vessel = Curved surface area of cylinder + curved surface area of the hemisphere
= 22/7*21(2h + 2r) = 22*3 (18 + 42)
= 66*60 = 1320 sq.cm
